FASS Fuel Filters vs. The Competion: 3rd Party Test Results
July 15, 2020

We spent over $14,000 on 3rd-party testing to highlight the difference in fuel purity between FASS fuel filters and the competition.


The laboratory results showed a DRASTIC difference in water separation between FASS filters and our competition’s offerings. With vastly more water getting through, our competitor’s filters simply don’t offer the same level of protection for your injection system as FASS.
